Troubleshooting checklist
Have our team run diagnostics on your system to pinpoint the problem quickly and affordably.
Do you have zero production?
This is possibly the most common cause of low voltage. Ensure that there are no trees around and that the solar panels are not blocked by.
If shading is not an issue, most likely it will be the higher than normal operating temperature of the solar panels.
If your system was professionally wired, chances are that you may not experience this problem, but it is worth checking for.

Identify possible system issues
Panel defect
It’s uncommon, but panels may fail from time to time due to: hotspots, junction boxes issues, delamanation, etc..
Faulty inverter
Zero output is a common problem and in nine out of ten cases, it is due to a faulty inverter or charge controller.
Faulty wiring
If the modules are not overheated, the best bet for you will be to check for a bad connection.
